I have been out in the garage today considering how I will repair the top of the windscreen, where it really needs comprehensive surgery, but where the metal is frighteningly thin. I had thought of reinforcing the area with fillets of plywood inside the frame and fibreglass....but fibreglass and metal is considered a bad compromise as they don't stick very well and are thought to eventually separate.
So Now I am thinking of putting in a steel support and heat-sink.
Great to be back at it at last.
